Right after buying an used Yamaha XJ600N, I found that the rust in its fuel tank had clogged the fuel filter causing the motorcycle to lose power and until the engine died. The service station cleaned the fuel pump and replaced the fuel filter. One year later, I am worried about the condition of my filter as I don't want it to stop in the middle of a ride again. Is it possible to look at the fuel filter and figure out if needs replacing? Or does it come as a sealed unit that I simply need to replace based on some estimate?
I have done 2000 kilometres after having the filter replaced last year, and have made a conscientious attempt to keep the tank full most of the time. I live in a cold country where it snows in winter, so I only rode it three or four times in winter, but I kept the motorcycle in a relatively warm garage.
